Definitions

  • the present invention relates to the field of the control of the flow of a liquid in a conduit, a pipe or similar and relates to a control device for the throughput in a conduit portion or similar.
  • check valves or butterfly valves are already known in which the throughput is controlled by means of a discoidal body fitted in a conduit portion, and mounted on a rotary shaft, allowing it to be displaced by pivoting between a closed position in which it totally blocks and obstructs the passage (a position which is generally perpendicular to the flow direction) and an open position, perpendicular to the previous position and in which it opposes a minimum resistance to the flow of liquid.
  • valves or flaps are in particular described in the French patent application No. 00 02644 and in the patent application PCT No. WO 01/16473 in the name of the Applicant.
  • FR-A-2666395 discloses a control device having four pyramidal obstructing structures.
  • FR-A-2575518 discloses a control device providing a regulation by means of an obstructing structure having surface cooperating with the valve body. Such surface progressively moves away from the surface of revolution defined by the valve body.
  • GB-A-2120755 discloses a control device having obstructing elements that extend over the whole cross section of the duct.
  • the present invention relates in particular to overcoming the above-mentioned limitations and providing, in particular a simple solution in response to the above-mentioned aim.
  • the invention relates to a control device according to claim 1.
  • Figs. 1 and 2 of the attached drawing 4 therefore show a control device for the throughput in a conduit portion 1 or similar, comprising a valve or flap composed of a body 2, substantially of the plate type or similar, formed or rigidly mounted on a shaft 3 for support and rotation and displaceable between a maximum closure position, possibly complete closure, and a minimum closure position by rotation about said shaft 3, the latter being rotated by an external member.
  • a control device for the throughput in a conduit portion 1 or similar comprising a valve or flap composed of a body 2, substantially of the plate type or similar, formed or rigidly mounted on a shaft 3 for support and rotation and displaceable between a maximum closure position, possibly complete closure, and a minimum closure position by rotation about said shaft 3, the latter being rotated by an external member.
  • At least one shape or structure 4, 4' which is at least partially obstructive, projecting into the internal passage of said conduit portion 1 and locally reducing the passage section of the latter, is present in the region of the internal face of the wall 1' of said conduit portion 1 and comprises at least one cooperating surface zone 5 which intimately mates with the shape of at least one part of the imaginary surface swept by at least one segment of the external peripheral edge 6 of the body 2 of the valve or flap when pivoted.
  • the cooperating surface zone(s) 5 of said projecting obstructive shape or structure 4, 4' extends/extend from the zone 1" of the internal face of the wall 1' of the conduit portion 1 in contact with the body 3 of the valve or flap in maximum closure position, and at most to the plane comprising, on the one hand, the rotary shaft 3, and on the other hand, the flow direction D or the longitudinal axis X of said conduit portion 1.
  • the passage section as seen by the liquid circulating in the conduit portion 1 will therefore be defined in cooperation with the body 2 and the obstructive shape(s) or structures 4, 4'. Said section can easily be visualised by projection onto a plane perpendicular to said flow direction D.
  • the evolution of the passage section and therefore of the throughput as a function of the inclination of the body 2 of the valve or flap can be modified or adapted to very varied profiles, with progressions (continuous or otherwise), limitations, etc.
  • the configuration of the cooperating surface zone(s) 5 of each obstructive shape or structure 4, 4', possibly sub-divided into several distinct regions, is such that the total length of the line or strip portion(s) of this zone or these zones which is or are in contact with the body 2 of the valve or flap for each position thereof in a given angular range, decreases when said body 2 is pivoted from its position of maximum closure toward its position of minimum closure.
  • each shape or structure 4, 4' has an appearance which is tapered from its base (in the region of the internal face of the wall 1) towards its peak (innermost end) and therefore the passage section increases more and more rapidly with the rotation of the body of the valve or flap 2 towards its open position.
  • the cooperating surface zone(s) 5 extends/extend, as viewed from the body 2 of the valve, over an angular range of at most 45° from the maximum closure position perpendicular to the flow direction D or the longitudinal axis X of the conduit portion 1.
  • each projecting obstructive shape 4, 4' has at least one cut-out, one indent 7 and/or one through passage in the flow direction D, opening in the region of the cooperating surface zone 5 and in cooperation with the body 2 defining the passage section of said conduit portion 1 in the region of the relevant valve or flap, when said body 2 of the valve or flap is in contact with the said shape 4, 4'.
  • At least one indent or cut-out 7 extends to the internal face of the wall 1' of the conduit portion(s).
  • said control device comprises two obstructive shapes or structures 4 and 4' situated on either side of the plane containing, on the one hand, the flow direction D or the longitudinal axis X of the conduit portion 1 and, on the other hand, the shaft for support and rotation 3 of the body 2 of the valve or flap, the one upstream and the other downstream of said rotary shaft 3.
  • the obstructive shapes and structures 4 and 4' will have different types of constitutions and exterior appearances such as, for example, a hollow or solid body, a simple wall portion or voluminal body, a profiled view or otherwise, etc.
  • each obstructive shape or structure 4, 4' has, as viewed in section in planes perpendicular to the rotary shaft 3, an angular configuration with one side in the form of the arc of a circle corresponding to a or the cooperating surface zone 5, said angle being directed upstream for the shape or structure 4 located upstream of the rotary shaft 3 and directed upstream for the shape or structure 4' located downstream from the rotary shaft 3.
  • each shape or structure 4, 4' can obviously comprise a plurality of indents of this type, optionally with different shapes, sections and sizes.
  • each obstructive shape or structure 4, 4' is connected on the internal face of the wall 1' of the conduit portion 1, by mechanical fixing, adhesion or otherwise.
  • each obstructive shape or structure 4, 4' is produced in one piece with the wall 1' of the conduit portion 1, if necessary obtained by deformation of this wall 1'.
  • conduit portions 1 of various sections associated with valve or flap bodies 2 with corresponding shapes, in particular: rectangular, square, elliptical, or other.
  • the body 2 of the valve or flap will have a circumferential discoidal configuration or circular peripheral edge 6, the cooperating surface zone(s) 5 of the obstructive shape(s) or structure(s) 4, 4' being supported by a sphere.
  • the obstructive shapes 4 and 4' form evolutional profiles with a spherical contact surface zone 5 resuming the curve of the body 2 of the flap.
  • the cooperating surface 5 is sufficiently close to the flap to have friction contact therewith and to thus ensure sealing during opening of the flap.
  • the shapes 4, 4' are only active at the start of opening the flap (cf. Fig. 1 ).
  • Fig. 3 shows, in a comparative manner the evolution of the throughput as a function of the opening of the body 2 of the flap for a same conduit portion 1 with and under shapes 4, 4' for a constant input pressure.
